Word count: 4533

✩

Silent yawns escape my mouth as Ominis has found himself stuck, yet again, rambling on about our N.E.W.T.S and what we should be doing to prepare.

Sure, I and Sebastian came to him about this willingly, but who knew we'd still be here 3 hours later, half of the time full of sheer complaining and stressing.

Well, we did. But it didn't seem as bad in the moment..

I puff my lips out and pierce my eyebrows together at Sebastian, expressing my regret. He responds by rolling his eyes at Ominis' endless rant, shutting them in shared exhaust.

I'd 100% usually be fallen asleep by now, but with Sebastian here, the frequent brush of his knee against mine kept me awake.

I stretch my arms up with a bend of my elbow to regain my strength, but the grip of my fingers grow weak, dropping the fountain pen I held in my hand onto the floor.

My foot seemed to have kicked at just the right time, because I felt my pen bounce off the toe of my shoe, landing farther beneath the desk.

I groan at the realization, rubbing my eyes before I get up and slide lazily under the desk. My whole body is cramped from sitting here for so long, knowing when Ominis' verbiage will end... Who knows.

"What are you doing?" Ominis pauses in the middle of his complaining, wondering what all the commotion and movement of the desk was about.

"I dropped my fountain pen." I respond, not expecting an answer in return as he supports my factor by continuing on his rant.

I shake my head with a small smile, kneeling under the desk, eventually having to go on all fours to be able to be in reach of the pen.

Just as I carried my hand out to grab it, Sebastians' shoe brushes in front of the pen, plugging my reach. He drags it back under his chair with the toe of his shoe, causing me to roll my eyes.

I crawl further toward beneath his chair, my knees lightly bruising due to the hard floors.

But just as I went to grab it, again, his measures deter me from doing so.

Except this time at the sense of his contact.

His finger brushes across my temple, gradually dragging the hair which hung in my face, behind my ear. My breath hitches in my throat, driving my whole body to freeze at his touch. My stomach flips as I look up at him hesitantly, ingesting the lump in my throat before our gaze is conveyed.

Immediately tension sparks up like crazy, provoking my chest to heat up and my heart to race. The position of which I'm in stains me nervous, not recognizing how close I am to his crotch.

We both seem to gape open our mouths in a shared heavy exhale due to the way he was looking down at me and I was looking up at him.

He blinks twice quickly whilst looking away, his chest displaying his breathing's gotten heavier. My teeth gnaw at my bottom lip as I look away, ultimately seizing the fountain pen.

He pushes the palms of his hands against his thighs downward in a stress. But when I went to move my view back onto him, something else jammed my vision.

The considerable bulge in his suit pants meet my eye, his hand sliding down slowly in an endeavor to cover it discreetly. Once I look back up at his face, red is STAINED all over, his spotted freckles painted additionally defined.

His jaw is clenched hard and has his tongue resting at the roof of his mouth in an attempt to keep himself together, avoiding eye contact.

I return back to my seat, clearing my throat as I sit down. I fix my skirt which rested over my legs with a few pats, sliding my hands down them in thought.

Both of my throbbing heartbeats make it hard to sit suitably, especially my second one, clenching my thighs jointly and modifying my position uncomfortably.

I find myself chewing on my lip a lot harder, deciding to act. I taste the blood rushing to my lip, it not stopping me from biting any harder.

I scoot my chair back and look over at Sebastian, who's feigning to listen to Ominis by providing frail, half-assed replies in order to mask his embarrassment. It was obvious he was avoiding eye contact, still making himself very aware of my actions in his peripheral vision.

I look away and lift up my left leg, my skirt lifting and exposing more than just enough of my underwear. I notice him look my way in the corner of my eye, almost instantly returning his view back onto Ominis in small panic. His leg begins to bounce more and more the additionally nervous he gets.

Suddenly so timid.. I thought to myself with a smile, unlacing my shoe.

Ominis found himself stuck in thought, buying me time.

Acting on my lust... Publicly... Good idea? No. But there's no stopping me now.

My leg returns to the floor, scooting myself back into the table. My hands slide on each side of my hips, fixing my skirt once again as my right foot slips my loose, untied shoe off.

I rest my cheek in the palm of my hand, carelessly sliding my socked foot up just above his ankle. I rub my foot up slowly, progressing a bit higher, lifting the hem of his pants up slightly.

I press my lips together as I rub the side of my neck, pretending to listen to Ominis just as Seb did.

"What do you presume is considerably mandated regarding a passing grade?" I ask Ominis, being entirely transparent toward my acting of 'doing nothing' to Sebastian.

My leg slowly makes its way up to Sebastians' knee, now FEELING his eyes carving into mine. I don't return his gaze, but that doesn't stop him from staring. I'm 'bout at my limit from as far as my leg can stretch onto his, so I just continuously rub it on the side of his knee slowly.

But once he finally looks away, he pushes his chair more into the table, as much as he can, giving himself to me fully.

Now that he's in reach, excitement & nerves fill my chest, needing my desperation to be fulfilled. But now that I know he gave himself to my reach willingly, I can mess around. Drive us both off the border.

Let's see if he's as up to game as I am..

Finally my foot glides up his thigh, stopping just before his print, causing his back to straighten in edge. He begins to bounce his other leg in anticipation, darting his eyes my way again, coldly.

This time our eyes meet, and he nearly pleads with his mere gaze, trying to figure my next move. Just as I'm about to slip my foot off of him, his wrist forms a fast, and tight grip around my ankle, pulling me back into my old spot. Thankfully, we weren't far enough away from each other for this to cause me to slip.

He doesn't let go of my foot, loosening the grip to move his hand to the side of my ankle, sliding up my leg. His fingers then brush lightly onto my skin, past the end of my black sock. The tips of his fingers glide softly and slowly up my leg, 0 pressure enlisted.

Our skin-to-skin contact sends bolts up my spine, tingling sensations initiating like a ball of spark in my gut.

The delicate brush of his fingers originate goosebumps like a trail, based on the navigation of him tracing up my leg. I accidentally let out a faint whine, already withering under the touch of his mere fingertips. I'm not as vital as I'd believed.

His eyebrows raise at the minuscule noise that came from me, slightly tilting his head to the left, as in question of 'what was that?'. I allow my teeth to sink into my bottom lip at the small growing grin plastered his face.

Is this a game..?

His hand slips under my thigh, causing me to clearly bite down on my lip harder, straightening my back with shakier-than-before breaths.

I look away, taking my foot off of his leg, causing his hand to slip away from mine.

He was leaned into the table in order to reach my thigh, but his naturally long arms and hands made it easier for him. He stayed in this position, bringing his newly released arm above the desk, resting his elbow on it.

Ominis never really persisted this lengthy, but N.E.W.T.S seemed to frighten him on a whole other level. He was more so worrying and studying with himself rather than us, so it was known we didn't have to answer or talk with him as frequently as usual. We were just there for support at this point.

Sebastian decided to use this to his advantage, standing himself up to walk over and sit next to me. His chair was placed dangerously close to mine, separating his legs into a man spread. His leg brushed up against mine.

He was getting needier and needier every minute that passed without any kind of touch or interaction toward him. As much as I did that purposely just to drive him off the edge, it was making me just as desperate as him. Almost.

He hums in frustration next to me, resting his cheek in the palm of his hand as he began bouncing his leg in anticipation again.

Not one word was said between the two of us in a good 20 minutes, and all I wanted was to be breathless in his ear, maybe somewhere alone.

I swallow the lump in my throat in reaction to all the completely unholy thoughts swarming my mind.

The sudden feel of Sebastians' finger brushing past my thigh again instantly make my cheeks go hot. I press my lips together harshly, the higher his fingers trace. His hand lifts up to slip over mine, which was resting on the top of the desk, carrying it over to his leg. He guides my hands over to his thigh, stopping right before his bulge.

I take a shaky breath, not facing his way. He leans over until I feel his breath hovering right next to my neck, speaking up. "Don't do that. Touch me."

His words drive my heart to sink into my stomach, a swarm of all types of butterflies flying in my gut bring me physically ill, but in the best way there is.

My gaze fixates onto Ominis, him being too invested in reading over his studybooks to have any idea of what's going on. I raise my chin a tad higher, swallowing the 20th lump in my throat of the day.

Sebastian exhales, almost in a whine, next to me, causing my breath to act up again. He fiddles beside me, adjusting his pants uncomfortably due to the raging boner risking to escape his tight pants.

He tries to guide my hands over his print again, but once he gets a little too close I shoot him a glare, causing him to stop. His hand grows warm on top of mine, his mere eyes pleading me. It's his turn to swallow the lump in his throat, feeling weak for begging, but his desperation gets the best of him. "Please, please touch me." He almost hesitates as he whispers, but he's tired of the wait.

I clench my jaw, knowing I'm giving in. I look at the library around us as I move my hand onto his print, examining the people around us. Which was nobody.

Ominis was mumbling to himself as he felt over the brail of his textbook, the corner we were in completely empty, not a person in sight anywhere around us.

That didn't matter anyway, my hand was under the desk and out of anyone's sight as I began to slowly stroke the bulge in his suit pants.

I feel his dick twitch in his pants at my touch, showing me how bad he's been throbbing for me all day, only at the mere rub of my foot or look of my face.

His mouth hangs open as soon as my hand glided over it, his breathing pace already picking up. He mouths the word 'fuck' as he tilts his head back, his needs finally being fulfilled slightly overwhelming him.

I try to contain the shock through my body with how large it felt in my grip, doing my best to keep my breath at a steady pace. I've been thinking about this for way too long.

I can see it on his face there's so much he wants to say, and so many noises he wants to make, but he conceals them due to our friend at the end of the table just in front of us.

His hearing majorly makes up for his loss of eyesight, but thank merlin for his distractions, or else who knows what he would've heard.

I pick up the rate on my through-the-pants stroking, him piercing his lips together to conceal any noises he longs to make. I soon bring my fingers up to his flyer, fiddling with it as I lean into his ear. My lips nearly brush over the lobe of his ear, whispering in it.

"You want more?" My heart races a bit faster with every word I whisper, scared it may not be quiet enough. Sebastian nods slowly, breathing heavily through his mouth at the longing anticipation. The nod of his head causes my nose to brush against his ear, my face getting closer to the side of his.

"How bad?" I ask quietly, my whisper almost at an unheard level of low. I examine his face, noticing he almost immediately pressed his lips together harshly at my question. His eyebrows knitted jointly as he clenched his jaw, taking a moment before answering.

He slightly moves his face toward mine, but not entirely, or else our faces would bump into each other. Our eyes meet, the tension thickening throughout the air.

"Don't do that, c'mon." His voice hears raspy and low, slight embarrassment peering through. He hated begging and that was easy to tell, it made him feel small. That never stops him though.

But me.. I love whiney, beggy men. But I also love men who know what they want and aren't shy about it. Which is exactly him all at once.

I just wanted to hear it from him one more time. I've been yearning to hear how bad he needs me for years. Literal years. Just once more and I'll happily give myself to him.

Before I can answer him he keeps his gaze on mine, strictly, causing me to forget my words. But instead, he speaks up for me. "You want this as bad as I do. I wanna hear you beg if I am." he responds breathlessly, his eyes darting between my eyes and my lips, his parted.

Our heads tilt, leaning into each other slowly. Both of our mouths are gaped open, lips parted. We no longer look each other in the eye, our gaze directly placed onto each others lips.

Our heads cock to the side in order to place our mouths at a certain direction of which would perfectly joint like a puzzle piece, but whenever our lips would almost brush against each other, I'd back away, causing him to continue leaning in.

He groans quietly to himself at the frustration of not being able to feel my lips against his. All I can think of when I look at his; is how soft yet passionate our kiss would be, yearning to glide my lips against his like rich silk.

But I was stubborn. It feels as though we had a game going, and I didn't want to lose. I wish to tease him until I drive him mad, having him beg on his knees in front of the whole library just for me to touch him again. But of course, he was just as stubborn. And realistically, I could never imagine him doing that. Or- I surely could... But, he wouldn't.

It didn't bother me. I just wanted to see how far this could go, regardless of MY desperation as well. Utter, desperation.

"Quit teasing me, y/n." His voice goes surprisingly dominant, honestly impressing me with how he can go from whiney and beggy to tough and demanding. But that was just Sebastian. And the switch in me was confused and slightly tweaked, but nonetheless going absolutely feral.

"Or what" I whisper back in an identical tone, gaining his eyes to lowen in a cold manner. "You'll regret it... That you will." he finishes, sending one last glance to my lips before leaning away from my face.

I wondered how he could gain back his courage and overall sanity after I've been, well- trying at least, to throw him off edge. What happened to needing me to touch him?

I hum in response, almost jumping at the voice of Ominis aside from us.

"Can you go one hour without threatening each other?"

"When we're stuck listening to you for the remaining three hours, undoubtedly." Sebastian responds rather quickly, unstartled.

"Sebastian, I require your assistance. I'm doubtful this was translated correctly." Ominis requests at the sound of his voice. I look over to Sebastian who looks at me, hinting to stand up.

I get up to move out of his way, allowing him to scoot down the bench to be seated in front of Ominis..

But once I stand up and begin to scoot in front of Sebastian off the bench, I feel his arm wrap around my waist from behind, his hand resting on my stomach, lightly pulling me down onto his lap. I softly gasp at the feel of his large print on my ass, grabbing his arm.

"I'm rather occupied studying a book, Ominis." He denies Ominis, His arm wrapping around my waist with a harder grip. I feel his breath suddenly by my ear, driving me to turn my head away from the heated breath a bit.

"You're gonna listen to me now." Sebastian orders and I nod, sighing in defeat. Of course, I lost in my own game.

Sebastian adjusts his hips more comfortably, causing me to squirm in his lap. I lift my ass off the hard boner I happen to be seated on, but he immediately drags me back onto him.

He grabs the book I suggested to him earlier in the week, and opens it to where he left off. He handles the book in his left hand, and me in the other.

His hand makes its way to my thigh, immediately bringing it up to my hip, where the strap of my underwear sat. He pulled his finger away from my hip, the strap of my underwear going along with it until he let go, snapping at my tender skin.

A small, muffled whimper escapes my pierced lips, planting a grin on his face. Our cheeks were pressed together, permitting me to feel the broad smirk across his face, making me huff.

I slide my hand on top of his, bringing it down my underwear. He stops my hand by refusing to allow his to follow mine.

"Please, we don't have time." I whisper breathlessly, my eyebrows curved up in desperation. I found myself beginning to worry about the time, knowing curfew.

I hear Sebastian growl with his throat, bringing his hand all the way down my underwear. He doesn't make any pit stops as I already feel his fingers separate as soon as they meet my lips, parting them.

The touch of his fingers playing with me, drive me insane. Shivers travel far up my spine at his touch, not giving me a moment to breathe whilst he already motions circular around my clit. He doesn't hit it, but that's purposefully to drive me off edge, maybe swiping past it here and there.

My legs squirm in need, endeavoring to conceal my complaints and whines. I grip his large forearm harder, venting my frustration. As bad as he wants to hear me plead and complain, he knows we can't.

I wish I could circle myself around him and rest my knees beside his hips, taking him in me as much as possible, riding him til we can't take it anymore.

His fingers rub up and down my slit, before almost instantly pushing both of his fingers into me, my walls immediately gripping around him tightly, fogging up my past thoughts.

I slam my palm into the bench on which we sat, shaking it slightly. He flips a page on his book with one hand, the other already deep in me. I don't know what his reasoning was to even have his book out at all, but my body is overflowing with all types of unprocessed emotions, still lingering from just minutes before everything to even care.

I notice Ominis glare up from his book toward our side of the table, opening his mouth to say something but stops himself, shaking his head whilst continuing to glide his finger across the magically brailled pages once again.

I close my eyes in both relief and pleasure, Gripping the front of the bench harder the faster Sebastians' fingers pump into me.

"Slo-" I try to tell him to go slower, but my words come out slurred and extremely slow. I give up because I find it too hard to maintain quietness, a small, low whimper escaping my lips in quit.

I drop the side of my head against his, our cheeks mashing together. He smiles at my attempt to speak, moving his face to be in my ear, feeling his lips glide against my cheek whilst doing so.

"We don't have time. Said it yourself." He whispers raspily directly in my ear, his tone heard daring and dominant. The number of curse words swarming in my head makes it incredibly hard to not voice out loud.. And moaning his name in my head is a little awkward... I wish I could do it in his ear. I wish I could show him how badly I need this, to my full extent.

He doesn't move his face, burying it in my neck and hair as he goes harder, faster. His fingers are far too deep inside of me for any noises to escape, but from my mouth, is a different story. I bring my arm around his shoulder, digging my nails into his suit uniform in order to conceal any noises that might make their way out.

The sensation of pure ecstasy and euphoria rise in me, becoming crazily overwhelming, my heart beat racing like no other. I've been rocking against his lap the whole time in rhythm with his fingers mashing inside me, without notice. His breath is a lot hotter and faster against my neck, and I feel him sew his lips shut, trying just as desperately as me to stay quiet. This helps me realize he's most likely getting off just as I am, the slight wet feel of pre-cum peering through his thick pants on my ass confirms my assumption.

He buries his head further into my neck, nibbling and sucking at my skin. I feel as if my heart is literally going to beat out of my chest, my breathing pace at its speed limit as I hit my peak, this euphoric feeling spreading throughout my whole body, causing my legs to shake uncontrollably above him. My leg hits the table harshly, but Ominis and what he was doing wasn't even on my mind, so I didn't care to look over at all.

I swallow my deep breaths, throwing my knees together in overwhelm as I disguise quieted whines from behind my jointed lips.

I do my best to be as quiet as possible, but him still pumping his fingers into me, along with his thumb rubbing against my clit throws me even further overboard, his hand slipping over my mouth just in time as I let out a muffled "fuck".

I feel wet fabric against my ass, guessing Sebastian came just about when I did.

He's breathing directly in my ear, keeping my pussy just as wet as before, possibly even more. My clit pulses intensely, and regardless of the relief in me, I yearned for more. Way more.

He finally slips his fingers out of me after we both catch our breath, the two of us looking over at Ominis to see his doings.

To our surprise he was knocked out on top of his book, his wand still in his hand.

Sebastian puts both of his hands on my waist, placing me off of him and back onto the bench. I can't control the whimper that leaves my mouth due to the sudden pressure of seating down so harshly on my pained, sensitive clit.

I turn my view over to Sebastian, noticing the mess of me on his pants, along with his beneath them, peering through.

"Merlin.." he says to himself breathlessly due to the thick puddle on his lap, adjusting his crotch as comfortably as possible.

I hum at the sight, causing Sebastian to turn his head toward me.

"Satisfied?" I regain my ability to speak, my words coming out breathless and raspy. My chest beats harshly due to my breathing, as his does the same.

"Not yet." He responds in the same heavy breath, slipping his hand around my waist, pulling me closer to him and kissing me hard, an unexplainable noise coming out muffled due to the sudden harshness, my whole body gone sensitive.

But the kiss.. Almost just as I expected. Passionate and glided just like rich silk, except hard and slightly aggressive. But I fucking loved it. His lips swallowed mine as I part my lips, deepening the kiss. His hand found the back of my neck, losing our breath nearly completely as he deepens it even more by pulling me harder into him, finally letting go to regain the air in our lungs.

My heart rate never slowed down, as it never did whenever I was by him. Tonight was intense, but not intense enough. I need him in me.

"Satisfied now?" I asked whilst attempting to stand up, my legs still twitching, making it hard to keep my balance. I feel his hand slip up my back in support before he stepped away from the table.

"Mmm." he hums in response, shrugging in unsureness. I use the table for support as I walk by with him at the corner of the table, going to wake up Ominis and get going.

"What do you need.." I roll my eyes, limping over to the side as he brushed past me. He leaned down into my ear, for like the 20th time in the hour, to respond.

"I need to be in you.." He says lowly, not in a whisper, but it's raspy and soft. He throws his robe over his shoulder as he walks over to Ominis, patting him on his back gently to get him up.

His words hit my core, causing my second heartbeat to pulse HARD, my knees going weak and causing me to stumble, using the table to hold me back up. Good god, the affect he has on me is crazy.

Sebastian ties his Slytherin robe around the front of his crotch after waking up Ominis, causing me to chuckle a bit.

Authors Note: Did I end this off on a rushed note? I'm so sorry if I did, I always find myself more invested in writing the build up LMFAO, and I'm just desperate to post this so I did slightly rush a bit, but if its that bad I can go back and edit it if needed.
